- Backup strategy for Data Protection for SAP HANA
To avoid data loss from SAP HANA databases, you must run full backups and redo log file backups regularly. - Optimization of Data Protection for SAP HANA performance
When SAP HANA backs up data, it sends data for all SAP HANA services, such as nameserver and indexserver in parallel from all nodes. If data is intended to go directly to tape, the number of allowed mount points for the Tivoli Storage Manager node must be adjusted. - Network performance optimization
When you are setting up the network, there are some items to consider that can improve network performance. - Backup server optimization
When you are setting up the Tivoli Storage Manager server, there are some items to consider to optimize performance. - Store data on the Tivoli Storage Manager server
In SAP terminology, backup (BRBACKUP) refers to the backup of data; archive (BRARCHIVE) refers to the backing up of log files. Data Protection for SAP uses the Tivoli Storage Manager archive function for backups and archives. - Planning for space required for SAP HANA backups
Before Data Protection for SAP HANA sends data to Tivoli Storage Manager, it notifies the Tivoli Storage Manager server of the amount of data that is going to be sent. This enables the Tivoli Storage Manager server to select the appropriate storage pool that accommodates this specific amount of data. - Parallel backup paths and backup servers
Data Protection for SAP can use several communication links between Tivoli Storage Manager clients to control alternate backup paths and alternate backup servers. This feature can increase throughput by transferring data over multiple paths simultaneously or to and from several servers in parallel. It can improve the availability of the Tivoli Storage Manager client to server communication and enable disaster recovery backup to a remote Tivoli Storage Manager server. - Archive inactive data
Data Protection for SAP creates a database image that is stored at the bit-level and can be used for routine backup operations. - Restore versus backup
Configuration changes and infrastructure problems affect backup and restore operations. - Create multiple redo log copies
Data Protection for SAP can save a number of copies of each redo log by using different Tivoli Storage Manager server management classes. By creating multiple redo-log copies on separate physical media, the administrator can restore and recover a database even if a backup tape becomes corrupted.
